WATER-RECORDER.

Specification of Letters Patent.

Patented June 27, 1911.

Application filed November 7', 1910.- Serial No. 591,191.

To all whom 'it may concern:

Be it known that I, CHRISTOPHER H. WAT- soN, a citizen of the UnitedStates, residing at- Riverside, in the county of Riverside and State ofCalifornia, have invented a new and useful later-Recorder, of which thefollowing is a specification.

This invention relates to means for recording the height of water inweirs, ditches, reservoirs, etc., and one of the objects of theinvention is to provide simple and efficient means for this purpose inwhich provision is made for successive use of different parts of therecord sheet.

The accompanying drawings illustrate the invention, and referringthereto: Figure 1 is a front elevation of the device with the frontclosure door opened and` the parts broken away. Fig. 2 is a plan of thedevice with the top door or lid open and partly in section. Fig. 3 is avertical section on line ac3- m3 in Fig. 2. Fig. 4 is a plan of thepencil-holding means with the supporting bars therefor shown in section.Fig. 5 is a vertical section on line c5- 005 in Fig. 4. F ig. 6 is ahorizontal section of a portion of the holding drum for the recordsheet, showing the manner of attaching the record sheet thereto. F ig. 7is an elevation of the lower part of the drum.

1 designates a case provided with a door 2 at the front and with a cover3 hinged to the top of the case. A bracket 4 extends forwardly from therear wall of the case 1 and is formed with a cup or socket 5constituting the lower or step bearing for a drum or cylinder 6 whichholds the record sheet 7 Said drum 6 has a pin S extending downwardly atits lower' end to engage in the cup or step bearing 5 and said cylinderhas a pin 9 extending from its upper end and engaging in a hole in anarm 10 extending forwardly from the rear wall of the case. Sufficientdistance is provided between the top of the drum 6 and the arm 10 toenable the cylinder to be lifted far enough to remove the lower pin 8from the bearing 5.

The drum cylinderv 6 is formed of sheet metal bent in cylindrical shape,with heads 12 and 13, said cylinder having a longitudinal slot at oneside, one end of the metal sheet being bent in at this slotand extendingbeneath the other end so as to form a channel 14 extendinglongitudinally of the drum. The record sheet 7 coiisisting, for example,of cross-section paper, is bent along one edge as indicated at 15 andthis bent portion is pushed into said channel, the body of the sheetbeing then drawn around the drum 6 and the said end being pushed intosaid channel 15 underneath the said bent end of the sheet, therebysecuring the sheet to the drum or cylinder 6.

The means for making the record consists of a pencil or`scribe 17secured in a clip 18 on an arm 19 carried by a vertical shaft 20,mounted in a carrier 21 which slides vertically on two guide rods 22carried by brackets 23 attached to the back of the case. A spring 24 issecured at one end to said carl rier and at the other end to the saidshaft, so as to tend to hold the pencil yieldingly toward the surface ofthe drum 6. The top of the carrier 21 is provided with a knob orprojection 26 over which the arm 19 may be pushed to position shown indotted lines in Fig. 4, thereby holding the pencil away from the drum,the spring 24 serving to produce a downward pressure on the shaft- 20and the arm carried thereby as well as a rotative effect. The carrier 21is connected to a float 30 by a rod 31, the upper end of this rod havinga collar 32 in which is slidably mounted a vertical rod 33 connected tothe said carrier, said vertical rod 33 having at its lower end a collar34 sliding on the vertical rod 31 connected to the float, a set screw 36being provided in the collar 34 to adjustably secure the said collar onthe rod 31 and thereby hold the pencil carrier in fixed positionrelatively to the float.

The upper head 12 of the drum or cylinder 6 is formed with a groove 36in which runs a cord 37, passing over pulley 40, and carrying aweight-41 at one end and passing at its other end around a pulley 42 onthe case and a pulley 43 on the hour shaft 44 of a clock indicated at45, and passing from said pulley 43 over a pulley 48 to a weight 49. Thelast named weight 49 is heavier than the iirst named weight 41 so thatthere is a continual tendency to draw the cord or belt in one directionand thereby rotate the drum by the action of the weights, the rate ofthe movement being regulated by the movement of the clock. A hook 50 isprovided in the case 1 to receive the cord 37, for temporarily holdingit out of Contact with the drum.

The device is used as follows: The case 1 is placed over the body ofwater or apparatus in which the level is to be recorded,

and the float bar 3l is adjusted with relation to the carrier 2l so thatwhen the water is at a certain standard level, for example, just at thecrest of the weir, the pencil 17 is at the proper height to mark on oneof the horizontal lines of the record sheet, for example, the lowestline thereof. The clock being set in operation, the drum G is rotatedcontinuously by the preponderance of the heavier weight 49, so that nodragging is exerted on the clock. rThe lighter weight Lll serves tomaintain tension on the cord 37, producing sufficient friction on thegrooved head 12 of the cylinder to cause the cylinder to rotate. Thepencil l? being moved into position in contact with the record sheet asindicated in full lines in Fig. il, it will in the rotation of thecylinder, describe a line or curve on the paper, the height of thiscurve above the base line indieating the elevation of the water abovethe standard level. lt is preferred to so proportion the speed ofrevolution to the dimensions of the cross-section lines on the paperthat each space on the paper represents one hour, and the completerevolution may conveniently represent one week. Viflhen one revolutionhas been made, the carrier supporting rod 33 is raised on the float rod31 a sufficient distance to bring it in alinement with anotherhorizontal line on the crosssection paper and fastened at such position,a second record being then obtained at a higher level, this operationbeing repeated so that the same record sheet may be used for a largenumber of successive weekly records, and when the sheet has been filledup in this manner it may be easily removed by opening the doors 2 and 8,pulling the cord 37 from the grooved head l2 of the cylinder 'g andhooking said cord over the hook on the case. The cylinder may then belifted up so as to remove its lower pin S from the :iv bearing 5 and onthen drawingthe lower end of the cylinder outwardly until it clears thebracket il, whereupon the cylinder may be lowered so as to remove itsupper pin 9 from the bearing in the arm l0. The record sheet may then bereadily removed from the cylinder by slipping out the lower inserted endand then the hook end of the record sheet from the channel l/l in thecylinder.

lVhat I claim is:

l. A water recorder, comprisii'ig a drum mounted to rotate on a verticalaxis, vertically extending guide means adjacent to said drum, a carriermounted to slide vertically on said guide means, a pencil mounted onsaid carrier, a float, a rod extending vertically from said float and asecond rod connected to said carrier and slidably connected to said rodon the float and provided with clamping means for adj ustably securingit thereto.

2. In a water recorder, the combination with the record drum of a guideextending vertically adjacent thereto, a carrier mounted to slidevertically on said guide, a shaft journaled in said carrier and providedwith an arm, said arm having pencil holding means, a spring connected tosaid shaft and to said carrier to hold the pencil toward the record drumand also to force the arm downwardly, said carrier having a projectionover which the arm may be moved to cause the pencil to move to or fromthe contact with said drum, said projection serving to hold the arm ineither position.

ln testimony whereof, l have hereunto set my hand at Riverside,California thisl 31st day of October 1910.
